KMail oddity after power failure

Hi All, The power went out this a.m. when I was editing an e-mail in KMail. When I later booted, reiserfsck replayed about 8 transactions on / and /home and everything appears to be normal. However, KMail is now popping up the little window, bottom-right, when I delete an e-mail... the same window that previously (I think) popped up only when KMail was retrieving new mail from the server via pop3. Is this KMail's normal behavior and I've just never noticed it before? Or, is there possibly a problem in KMail's folders I should be investigating? TIA & regards, Carl
